Area Deprivation Index by Census Block Group

The Area Deprivation Index has been publically released! The ADI map displays rankings of neighborhoods by socioeconomic status disadvantage in a region of interest (e.g. at the state or national level). It includes factors for the theoretical domains of income, education, employment, and housing quality. It can be used to inform health delivery and policy, especially for the most disadvantaged neighborhood groups.

Change in Area Deprivation Index Scores (2013 to 2015) by Census Block Group

This map layer displays the change (+/-) in Area Deprivation Index (ADI) scores between the 2013 and 2015 datasets. The ADI is a rankings of neighborhoods by socioeconomic status disadvantage in a region of interest (e.g. at the state or national level). It includes factors for the theoretical domains of income, education, employment, and housing quality. It can be used to inform health delivery and policy, especially for the most disadvantaged neighborhood groups. The 2015 ADI (v2.0) was constructed using the 2011-2015 5-year estimates from the US Census’ American Community Survey. The methods are identical to the 2013 ADI construction.

Location Affordability Index for Family at AMI

This layer displays the estimated percentage of household income for housing and transportation for a family earning the Area Median Income (AMI). The expected values for housing and transportation are modelled by HUD using data from the US Census Bureau and the US Department of Transportation, including:

  • The average household size for a family earning AMI in the nieghborhood
  • The average number of workers, vehicles, and vehicle miles travelled for a family in the nieghborhood
  • The average utility and rental costs or average utility and mortgage costs for a housing unit to accommodate the family size above
  • The proportion of housing units that are either rentals or owner-occupied in the nieghborhood

Note: The LAI does not predict what families are actually paying to live in a particular area, but rather what a family would pay (either in USD or as a percentage of income) if average or reasonable housing and commuting conditions for a particular neighborhood were achieved.
